I was working on this all day yesterday in fact. Flickr has very recently changed their authentication mechanism that is used to grant access to private photos. They used to have their own custom authentication, now they use OAuth (open authentication – similar to FaceBook, Twitter and LinkedIn authentication) however it is not working properly for me (probably a bug in my code). I may therefore have to push out the July release without the private photos feature unless I can get it working this morning.

Hi Allen, I do plan to add this functionality – however it does need significant instruction for the users to help set up their Flickr private key /signature. Flickr don’t make this easy.I had planned to do this in the May release but ran out of time. Aiming for the 18th June now.
